Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 32 points:

(1,2,5,8)(3,7,4,6)(17,18,20,25,21,24,29,23)(19,22,27,31,28,30,26,32);(1,3,5,4)(2,6,8,7)(9,10,12,15)(11,13,16,14)(17,19,20,27,21,28,29,26)(18,22,25,31,24,30,23,32);(10,13)(11,16)(14,15)(18,23)(19,26)(20,29)(22,30)(24,25)(27,28);(1,4,5,3)(2,7,8,6)(18,24)(22,30)(23,25)(31,32)
